Magnetoresistive effect element, magnetic head, magnetic reproducing apparatus, and manufacturing method thereof |
摘要 |
A magnetoresistive effect element, includes: a magnetoresistive effect film including: a magnetization fixed layer having a first ferromagnetic film of which magnetization direction is practically fixed in one direction; a magnetization free layer having a second ferromagnetic film of which magnetization direction changes with corresponding to an external magnetic field; and a spacer layer disposed between the magnetization fixed layer and magnetization free layer, and having an insulating layer and a ferromagnetic metal portion penetrating through the insulating layer; a pair of electrodes applying a sense current in a perpendicular direction relative to a film surface of the magnetoresistive effect film; and a layer containing a non-ferromagnetic element disposed at least one of an inside of the magnetization fixed layer-and an inside of the magnetization free layer.
